Numerical simulation of transient temperature field under the interaction between laser and metal materials

  • 摘要: 激光中心温度探测是激光领域的一个重要课题,直接影响着激光在工程技术中的应用。利用XL-800WF光纤传输多功能脉冲激光加工系统,照射厚钢板,得到钢板的熔化图。通过显微镜测量熔斑的直径,从而计算液态钢的凝固时间。根据激光温度的扩散原理,建立理想条件下钢板的热传导方程,模拟出钢板的温度演化规律。结合凝固时间,推导了XL-800WF光纤传输多功能脉冲激光中心温度的理论值。
